new kernel and other techie stuff

[kragen@pobox.com (Kragen Sitaker)]

Well, the new kernel seems to be working rather nicely.  Except that
the Sun doesn't netboot any more, and I can't tell why.  It
successfully rarps for its address and tftps the netboot program; the
netboot program successfully rarps for its address, gets its default
gateway and root filesystem via bootparamd, and loads the kernel via
NFS;  the kernel comes up to the point where it tries to mount the root
filesystem (apparently), saying:
enabling interrupts
boot device: le0
nfs_boot: trying RARP (and RPC/bootparam)
nfs_boot: client_addr=0xa0b124d (RARP from 0xa0b124c)
nfs_boot: timeout...
nfs_boot: timeout...
nfs_boot: timeout...
nfs_boot: bootparam whoami, error=60
no file system for le0
cannot mount root, error = 79
root device (default le0):

Meanwhile, tcpdump says

So it's sending bunches of 96-byte requests to the subnet broadcast
address RPC port -- perhaps for bootparamd?  I don't know why it's
doing that -- I'm sure that if it simply asked the bootparamd on the
host that just gave it the RARP reply, it would get an answer right
quickly.

I did compile rarp into the kernel this time instead of as a module,
and it is after all a much more modern kernel; I shall try rebooting
with the older kernel again in a bit.

Still no luck with the ALSA stuff; the drivers still refuse to load.  I get:
kragen:/lib/modules/2.2.12/misc# modprobe snd-card-ens1371.o
/lib/modules/2.2.12/misc/snd.o: unresolved symbol unregister_sound_dsp
/lib/modules/2.2.12/misc/snd.o: unresolved symbol register_sound_dsp
/lib/modules/2.2.12/misc/snd.o: unresolved symbol unregister_sound_special
/lib/modules/2.2.12/misc/snd.o: unresolved symbol register_sound_special
snd: No such file or directory
snd: No such file or directory

. . . despite the fact that these symbols are listed in the System.map
in the kernel source directory with Ts next to them.  Is it possible
I'm still accidentally booting the no-sound-support kernel?  Dunno.
I'll find out soon!

Marilyn has invited me to eat at Amar India with her; I have to be
there in half an hour.  Bye!
